# How to Recognize a Linear Pair

A linear pair is a straight line formed by a set of angles that have opposite angles. A linear pair is composed of a set of angles with opposite sides and non-common arms. Besides this, the two angles can also be known as supplementary or adjacent angles. The following paragraphs will explain these terms and their functions. They will be useful when you are trying to solve a math problem. In addition to this, you will learn how to recognize a linear pair when you encounter it.

## supplementary angles

A supplementary angle to a line is an angle that has the same sum as another angle. Hence, a supplementary angle to a line is one of the angles in a linear pair. It is also known as a right angle. The angle OC is part of a line segment PQ. Hence, two supplementary angles to a line segment PQ form a line. The sum of these angles is 180 degrees.

## Adjacent angles

Two angles that have the same vertex and side are said to be adjacent. These angles are known as supplementary angles. Their sum is always 180 degrees, and they form a straight line. A linear pair is a series of angles that have a common vertex and side. In mathematics, adjacent angles are always supplementary. However, the opposite is also true. Adjacent angles may not be supplementary.

## Angles that form a straight line

In geometry, a straight angle is a pair of right angles that share a common locus. The sum of two straight angles is 180deg. Hence, they are called straight angle pairs. This type of angle is a connector between two points. A straight line is a line that extends horizontally or vertically. Angles that form a straight line are the same length. However, the direction of a straight line is different from the angle’s compass.

## Angles whose non-common arms are opposite rays

Linear pairs of angles are formed when two adjacent angles have common arms and their sum is 180 degrees. Angles that form a pair are supplementary if they have the same vertex and have no interior points. This property makes supplementary pairs of angles easy to define and is very useful when solving mathematical problems. The next part will describe some examples of supplementary pairs of angles. It is easy to see that some angles have similar characteristics and others do not.

## Examples of linear pairs

What are examples of linear pairs? Linear pairs are adjacent angles that form a straight line. They are also known as supplementary angles because they add up to 180 degrees. Examples of linear pairs are shown in the diagrams below, as well as the solutions page. To help you learn more, view the video below! We will discuss what these angles are and how they are created. This video will also explain what is meant by supplementary angles, and the difference between adjacent and supplementary ones.
